William Alexander Brown MBE (13 December 1922 – 5 December 1984) was a British military officer based in British-ruled India. He is best known for his actions during the Partition of India, when he assisted the locals of the Gilgit Agency and led a coup d'état against Hari Singh, the Maharaja of the erstwhile princely state of Jammu and Kashmir. The successful coup ultimately resulted in the Gilgit Agency (in today's Gilgit−Baltistan) becoming a part of Pakistani-administered Kashmir following the First Indo−Pakistani War.
